Alright.
Thadeus Young last year was a disappointing starter. He played 32 mpg, averages 13.8/5.2/1.4. Not a building block. However, in his first game this year he stepped in for 26 minutes and got a 15/3/1. That's good bench production.
Ty Thomas is a guy who for Charlotte last year could step in in 22 minutes and give 10.1/6.1/.9. That's quite a bit better than 13.5/5/.5 in 32 minutes; I don't think anyone still looks for Ty Thomas as anything but a good rotation bench PF; certainly not a building block.
Derrick Favors, a rookie considered years away, stepped in for 20 minutes last nigh for an 8/10. That's great bench production.
Taj Gibson last year went for 9.0/7.5/.9 in 27 minutes. Not quite the scoring I referenced, but significantly better rebounding (which is more of what I want from a PF); regardless, the above line is quite a bit better than the 32 minute 13.5/5/.5 and Gibson was decidedly a very nice bench player last year.
Dejuan Blair, who I think everyone knows should be 6th man type big in an ideal situation, certainly not a building block, stepped in last year for 18.2 mpg and 7.8/6.4/.8
Kris Humphries, whom no one confuses as a starter, stepped into NJ last year for 20.6 mpg and a 8.1/6.5/.6
I like McDyess's '04-'05 as a comparison: Very solid and respected bench player, 23.3 mpg, 9.6/6.3/.9
Al Harrington came off the bench last night for 24 minutes for a 10/7/2. No one wants him starting.
A guy like Robin Lopez should Ideally be a 3rd big or your 5th best starter; last season in 19.8 minutes he contributed a 8.4/4.8/.1
It only took Channing Frye 27 mpg last year to get his 11.2/5.3/1.4. And he is decidedly not a bankable starter.
Here's the rub: Davis is a bench PF. That's fine. His shooting percentage is definitely going to decline, and once it returns to normalcy, he is going to need to improve in other areas to really justify 31 mpg or so.
If he is going to justify starters minutes, he either needs get up to a Nene (i think generally considered a "good starter")-type level to be considered a good PF starter: 12.2/7.0/1.2 in 26.8 mpg or 14.6/7.8/1.4 in 32.6 mpg. Or, if his rebounding is maxed out, and he's going to be a scorer, a truly great bench scorer is someone like maggette, who throws up an 18.6/5.6/1.8 in 31 minutes.
In other words, in order to justify his huge increase in minutes, Davis either has to increase his scoring even more than he already has, or drastically improve his rebounding. Until then, he's a solid bench player playing starters minutes.
As point of reference, last year Davis played 17.3 mpg and put up a 6.3/3.8/.6. Solid bench work. This year, he hasn't truly been much better; points per minute are up, assists per minute and rebounds way down and minutes is the thing that has gone way up, obscuring some of the numbers.
